ROI Case File No.190.5 | 7 Cooking Tools That Decode the OODA Loop

Prologue: Footsteps in the Kitchen

That evening, I received a peculiar case file. The sender was a head chef from a renowned traditional restaurant. "I want to learn data analysis, but complex theory books just don't sink in," he wrote.

Intriguingly, in his kitchen, seven seasonings were arranged—"Sa-Shi-Su-Se-So + Sake & Mirin"—as if they were telling the story of an OODA Loop.

Chapter 1: The Identity of Seven Tools

"Master Chef, every night you use these seven seasonings to complete hundreds of dishes. There's routine there, there's sequence," I observed.

I surveyed the spice rack in the kitchen. Sugar, salt, vinegar, soy sauce, miso. And sake with mirin.

"The truth is, this very sequence represents the most practical OODA Loop."

Chapter 2: Observe — Sake Reveals Truth

"Let's begin with sake," I suggested.

The chef's hand reached for the sake bottle. The fishy smell disappeared, and the earthy taste of vegetables faded.

"Sake in data analysis is preprocessing. It removes the 'odors' of outliers and missing data. To truly understand the nature of your ingredients, you must first eliminate the noise."

Just as sake reveals the true character of ingredients, preprocessing brings out the essence of data. The first step in observation is seeing what should be seen correctly.

Chapter 3: Orient — Building Foundation with Sugar and Salt

"Next comes sugar, then salt," I continued.

The chef's movements were efficient and purposeful. Sugar created the foundation, salt tightened the flavors.

"Sugar represents your data infrastructure. Google Analytics, Tag Manager, data warehouses. By setting this foundation first, all analysis comes alive."

"And salt is your adjustment mechanism. Search Console, heatmap tools, A/B testing platforms. Depending on the situation, these tools draw out the flavor of your data."

Without a solid foundation, even the finest seasonings become meaningless. The basis of situational judgment rests on these two elements.

Chapter 4: Decide — The Decisive Power of Vinegar and Soy Sauce

"Timing is everything with vinegar," the chef murmured. "Too early and the acidity evaporates; too late and it doesn't blend properly."

"Exactly. Vinegar represents the speed of hypothesis testing. It cuts through with sharp insight, responding quickly to market changes."

The aroma of soy sauce filled the kitchen—deep, complex, commanding presence.

"Soy sauce embodies the depth of strategic planning. It reads beyond surface numbers into customer psychology and competitive dynamics. Decision-making requires both the sharpness of vinegar and the depth of soy sauce."

Chapter 5: Act — The Finishing Power of Miso and Mirin

"Finally, miso and mirin," I concluded.

The miso dissolved, defining the dish's core and unifying all flavors into harmony.

"Miso is the essence of insight. The fundamental understanding derived from data. Without this, even the most beautiful dashboard becomes meaningless."

Mirin's glaze enveloped the entire dish with a beautiful, appetizing shine.

"Mirin represents presentation technique. Data storytelling, visualization, report design. It's the final touch that delivers insights to people's hearts."

Chapter 6: A Complete Story

A single dish was complete. Seven seasonings harmonized perfectly, maximizing the goodness of the ingredients.

"Master Chef, the OODA Loop is ultimately this kind of craftsman's technique."

I picked up chopsticks and took a taste.

"You observe to know your ingredients, orient to build your foundation, decide to set direction, and act to create value. What you practice in this kitchen every night is the most sophisticated data analysis methodology."

Epilogue: The Detective's Insight

Later, the chef mastered data analysis brilliantly and improved his restaurant's revenue by 30%. When asked about his secret to success, he replied:

"If you get the sequence of seasonings wrong, the dish is ruined. Data analysis was the same. Follow the steps, watch the timing, and finish carefully until the end. That was all there was to it."
